EYELETlNG-IVIACHINE.

SPECIFICATION forming part of Letters Patent No. 773,845, dated November 1, 1904.

Application filed Ju1 20, 1903.

To all whom. it may concern:

Be it known that we, JOSEPH WV. BARNA and VALENTINE HOFFMAN, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Eyeleting-Machines, of which the following is a specification.

This invention relates to improvements in machines for setting eyelets, and particularly to the means for punching or forming the apertures in which the eyelets are to be secured.

The invention comprises generally, in combination with the usual stationary and movable sets of an eyeleting-machine, a punching mechanism cooperating therewith and designed to cut or punch outeyelet-apertures in the stock to which the eyelets are ,to be affixed and then through the medium of a suitable connection with a moving part of the machine to be withdrawn or retracted to permit the sets to aflix the eyelets.

The invention further contemplates the provision of means for clamping or holding the stock in position for the setting operation to secure the same against movement upon the withdrawal of the punching mechanism and insure the alinement of the apertures in the stock with the spindles which pick up and deliver the eyelets to the sets. Means are also preferably provided for throwing out of operation one or more of the ll I sets and the punching mechanism associated therewith in order to vary at will the number of eyelets aifixed at each operation.

The above and other features and improvements are hereinafter fully set forth, and particularly specified in the appended claims, and are illustrated in the accompanying drawings, in which Figure 1 is a side elevation of an ordinary eyeleting-machine, showing my invention applied thereto. Fig. 2 is a side elevation of the front portion of the machine with the parts in the positions they occupy during the punching operation. Fig. 3 is a similar view, but with the punching mechanism retracted and the sets in operative position. Fig. 4: is

a rear elevation of the punch-block or anvil which cooperates with the punches, showing the springs for restoring the parts after each operation. Fig. 5 is afront elevation of the upper and lower" sets, the punches, and punchblock, the parts being shown in their preliminary positions. Fig. 6 is a vertical section, partially in elevation, on the line 6 6 of Fig. 5. Fig. 7 is a section on the line 7 7 of Fig. 6. Fig. 8 is a vertical longitudinal section on the line 8 8 of Fig. 6, showing the lower or movable sets and their associated eyelet-spindles, together with the lower member of the stock-clamp. Fig. 9 is a plan of the lower sets and clamp members, the set of each end of the series shown as capable of be ing thrown out of action. Fig. 10 is a detail of one of the punch devices. Fig. 11 is aperspective of one of the end or independentlymovable sets of the lower series also seen in active position in Figs. 5 and 9; and Fig. 12 is a fragmentary view of the upper portion of the carrier for the movable sets, illustrating the arrangement of the slots in which the finger-pieces attached to the end sets are adapted to move in throwing the end sets into and out of operation, the springs for holding the finger-pieces not being shown.

In the drawings the invention is shown as adapted toa setting-machine of ordinary construction and comprising the following mechanism: The base 20", on which the machine is mounted, is provided with a head or standard 25, carrying the usual raceway 23, provided with ordinary eyelet-stops 24 for delivering eyelets to the setting mechanism and which is supplied with eyelets from a reservoir or other receptacle 21 in the ordinary manner. The raceway is retracted by a cam- (not shown) keyed on the driving-shaft 22 through the medium of a lever 23, pivoted to the head, as at 24, and also, as at 25, to a frame 26, slidably mounted on the head. A spring 27 Z anchored to the head 25 and the lever 23*, serves to advance the raceway after it has been retracted by its actuating-cam. The upto the under face of an arm 20 of the head 25.

The verticallyreciprocating carrier 28, upon which the lower sets are mounted, slides in ways 29, formed in extensions of thehead 25, motion being imparted thereto by means of a lever 30, pivoted, as at 31, to a link 32, in turn pivoted tothe carrier at 33, as shown in dotted lines in Fig. 2. The lever 30 is rocked by an eccentric mechanism hereinafter to be described. The sets 34 of the lower series are secured in the sockets 35 in the carrier 28 and are hollow, having seated therein the usual spring-supported spindles 36, designed to pick up the eyelets from the raceway and deliver them to the sets.

The parts hereinbefore described are of the usual construction, except as hereinafter pointed out, and further description thereof is not thought to be necessary.

In carrying out our invention we provide a novel device or mechanism for punching the eyelet-apertures in the stock and which is so mounted as to be automatically and periodically advanced and retracted for the performance of its functions. This punch mechanism comprises a series of punches and a punchblock or anvil cooperating therewith and one of which elements is designed to be forced upon or against the other to perform the punching operation. In the embodiment of the invention illustrated the said punches and anvil are mounted on acarrier and the punchblock is capable of movement relative to the punches and is moved againstthe same by the lower series of sets. Connection is made, preferably, with a movable part of the machine for retracting the carrier to withdraw the punches and block from the .path of the movable sets when the latter close upon the stationary sets and also for advancing the punching mechanism upon the separation of the sets for the next punching operation.

In the construction illustrated there is pro vided a slide-block or carrier 37, located at the rear of the upper sets-block 21 and parallel therewith and having fixed thereto at each end a forwardly-projecting rod 38, which passes through and slides in an aperture 39 in the adjacent end of the block 21. Connection with a moving part of the machine is made for sliding theblock 37 in any suitable manner, as by means of the links 40, having hooks 41 at their forward ends engaging eyes 42 on the ends of the block 37 and pivoted at their rear ends on studs 43 at the opposite sides of the raceway, passing through elongated apertures 44 in the said links 40.

Formed in or on therear face of the block 37 are vertical grooves 45, Fig. 6, and seated in such grooves are the slide bars 46, by which the punch-block or anvil 47 is supported. In the present construction the anvil 47 is made in three sections 48, 49, and 50 for a reason hereinafter to be mentioned, and the central section, or 48, being considerably longer than the others, is provided with a pair of the vertical bars 46, one at each end, in order to properly guide and avoid lateral movement of the same, while the narrow sections are provided with one slide-bar 46 each. A plate 51, secured by screws 52 to the block 37, retains the bars 46 in position and is provided with a number of vertical slots 53, one of which is located at the rear of each of the bars 46 and through which projects a pin or stud fixed to such bar, as shown in Fig. 4. A cross-head 55 is located on the rear face of the plate 51 and engages the pins 54 of the slide-bars 46 and is provided with vertical stems 56, which pass through guide-apertures 57 in a rearward flange 58 of the plate 51, and coiled about the stems 56 are expansionsprings 59, which react against the cross-head 55 and the flange 58, exerting a constant tendency to hold the anvil in its depressed position, such position being defined by the ends of the slots 53.

It will be obvious that the block 37 and plate 51 might be made integral and provided with the necessary grooves and slots; but the arrangement described is thought to be preferable as being easier to construct.

Secured to the front of the block 37 (clearly shown in Figs. 2, 3, and 6) are the punch devices 60, one for each pair of cooperating sets. Each of the punch devices 60, as shown in Fig. 10, comprises a bracket 61, secured by screws 62 to the said block, a forward extension or lug portion 63, and the punch 64, extending downwardly from the under face of the extension 63 and having an aperture 65, the upper end of which is inclined forwardly, as shown in Fig. 6, to permit of the escape of the punchings as they accumulate in and are forced upwardly through the said passage. The punches 64 are coaxial with the sets, as shown in Figs. 6 and 7, and to properly position the same a spring 69 may be provided and attached to the arm 20, so as to engage the carrier and press the slide 37 into snug engagement with the block 21. In order to better resist the thrust of the lower sets during the punching operation, as hereinafter described, the punches 64 are located close up against the upper sets, being provided with recesses 66 to receive the tips 67 of the upper sets, the shoulders of the said sets resting against the shoulders, surrounding the said recesses. The construction not only prevents breakage of the punches, but in addition and by reason of the recesses 66 puts the wear on the shoulders of the sets 22, so as to prevent injury to their tips 67 and also permits the punches to be readily retracted, clearance being provided for the tips 64 by the said recesses.

The punch-block or anvil 47 extends forwardly from the slides 46 and has a flat upper face on which the stock is held and against which the punches act. The under face of the punch-block is provided with pockets 68,

designed to receive the eyelets on the spindles when the lower sets engage the punch-block to avoid crushing of the eyelets, and these pockets are preferably inclined upwardly toward the front upper edge of the block, as shown in Fig. 6, so that when the anvil is retracted it will slide off the ends of the spindles 36 gradually in order to prevent the latter being released suddenly so as to throw off the eyelets carried thereby. The shoulders at the sides of the grooves 68 are designed to be engaged by the shoulders or upper ends of the lower sets as the latter rise, whereby the an vils are moved upwardly against the punches to cut the apertures in the stock.

The eccentric mechanism previously referred to for operating the lower sets is designed to raise the latter into engagement with the punch-block 47 and after pressing the said punch-block against the punches pro vide a relief for the said punch-block and punches, so that they may be separated far enough to afford a clearance for the stock onthe retraction of the punching mechanism. While we do not limit ourselves to the particular means shown, we have illustrated in the drawings (see Fig. 1) a novel form of eccentric accomplishing the several necessary steps or movements. This eccentric comprises a disk 92, provided with a radial slot 93, in which is slidably mounted a hub portion 94, fixed on the shaft 22". The shaft 22 by reason of the radial slot 93 is eccentric to the disk 92. The latter is also provided with a groove 95, which is a continuation ofthe slot 93 and receives an arm 96 of the hub 94, the said arm at its end being preferably provided with an antifriction roller 97. The length of the hub and arm, with its roller, is substantially equal to the diameter of the disk 92, and the eccentric-strap 98, inclosing the latter, is provided at a suitable point on its inner face with a recess 99, the purpose of which will be hereinafter explained. The eccentric-strap is provided with an arm 100, to which is pivoted the rear end of the lever 30.

In the operation of the machine the eyelets are delivered to the raceway 23 in the usual manner and held in such position as to be in the path of the spindles 36 as they rise with the lower sets. During such upward movement and while the hub-arm 96 of the eccentric is moving from a to 5 (indicated in Fig. 1) and after the eyelets have been picked up by the spindles 36 the raceway 23 begins its retractive movement,being actuated by the lever 23. Before the studs 43 reach the rear ends of the elongated apertures 44 in the links 40 the punch-block 47 is engaged by the shoulders of the lower sets and pressed upwardly against the action of the springs 59, moving the stock, as shown in Fig. 2, against the punches 64, which, reacting-against the punch-block, cut the apertures. At this point the end of the arm 96 of the eccentric enters the recess 99 in the- 1 carrier 28 and the block 71.

eccentric-strap and the latter and the disk 92 are forced upwardly by an expansion-spring 101 reacting between the base 20 and the rear end of the lever 30 and slide on the hub 94 and its arm 96. This movement rocks the lever 30, lowering its forward end and moving the lower sets with it. This movement is only sufficient to permit the punch-block 47, under the influence of its springs, to lower far enough to provide a clearance between the punch-block and ends of the punches to permit the stock being moved off the punches before the latter begin their retractive movement and as shown in Fig. 1. The punching operation having been performed, the movement of the raceway will have carried the studs 43 to the rear end of the apertures 44 and then retracted the block 37 carrying with it the punches and block 47, and during such retractive movement the arm 96 of the eccentric moves along the recess 99, or from b to 0. Upon the retraction of the punches and punchblock the latter is pressed downwardly by its springs 59 in position to be advanced by the raceway at the proper time, the stock being held in such position that the apertures are in alinement with the spindles 36, which continue their upward movement with the lower sets. The eccentric continuing its rotation, the end of the arm 96 passes out of the recess 99 and the lower sets are then moved against the upper sets, and the eyelets having been passed through the apertures cut for their reception and moved onto the tips 67 of the upper sets the opposing sets are forced together and the eyelets upset in the usual manner. As the lower sets are receded the raceway advances again and when the studs 43 reach the forward ends of the apertures 44 advances the punch and anvil-carrierto its original position, as shown in Fig. 6.

Means are preferably provided to hold the stock in proper position after the punching operation and prevent its dislodgment by the movement of the punching mechanism. To this end we employ a pair of cooperating clamp members, one associated with each series of sets. One member, as 7 0, comprises a block 71, provided with apertures to receive the lower sets 34, on which it is slidably mounted. Coiled about certain of the sets ofthe lower series, as shown in Fig. 8, are expansion-springs 72, seated in' sockets 73 in the carrier 28 and reacting against the said Attached to or integral with the block 71 are fingers 74, which extend rearwardly between adjacent plungers, as shown, and in their normal position are disposed slightly below the upper ends of the spindles 36. The other member, 75, is

carried by the block 21 of the upper sets and is held thereto by screws 76, which pass through vertical slots 77 in a plate 78, on the lower end of which is formed or attached the rearwardlyextending fingers 79, adapted to cooperate with the lower clamp-fingers 74 and hold the stock. In the construction illustrated the outer fingers 79, which coact with the end or outer lower fingers 74, are provided with offsets having vertical apertures 82, through which pass the second set from each end of the upper series 22, and coiled about such sets are springs 80, one of which is shown in Fig. 6, which react between the block 21 and shoulders 81, formed at the upper end of the apertures 82, and hold the fingers normally slightly below the ends of the punches 63, as clearly shown in Figs. 5 and 6, the position thereof being defined by the upper ends of the slots 77 in the plate 78. When the lower sets-carrier 28 rises, it carries with it the lower clamp member 7 O, the fingers of which move past the anvil 47 in recesses 83 in the front face of the same and provided for this purpose and coacting with the upper clamping-fingers bear upon the stock with sufficient pressure to hold the latter securely, thereby insuring the alinement of the apertures with the spindles 36 after the punching mechanism is retracted. As the lower sets advance on the upper sets the upper clamp member is elevated, such movement being permitted by the slots 77 in the plate 78, and in the first or punching operation the clamping members assume the positions shown in Fig. 2. Upon the separation of the punch-block from the punches due to the relieving-recess in the eccentric the upper clamp follows the downward movements of the lower clamp and pushes the stock ofi the punches, so that the latter may be retracted, as heretofore described, without injuring the stock, and when the lower sets again rise to perform the setting operation the clamps assume the position shown in Fig. 3, holding the stock in proper position for the affixing of the sets.

The invention also includes means for varying the number of eyelets afiixed at each operation of the machine. Ordinarily difierent machines are .employed in eyeleting certain articles, such as shoe-uppers, when there is a variation in size or for other reasons it is desirable or necessary to vary the number of eyelets aiifixed. To avoid the use of a number of. machines for accomplishing this result, We have provided means in one machine for throwing out of action one or more of the sets, so that the machine will set any desired number of eyelets at each operation. This feature is claimed, broadly, in an application filed by us July 16, 1903, Serial No. 165,757, and in the present instance we claim the same only in combination with a movable punching mechanism, as herein set forth. One or more of the sets may be made capable of being thrown out of operation. In the construction illustrated two of such knock-out sets are employed. The sockets 84, in which the two outer sets 85 are located, are made deeper than the sockets of the inner sets, as shown in. Fig. 8, and the said sets are designed to he slid downwardly in such sockets, so as to be thrown out of action. Each of such sets 85 may be provided with a finger piece or trip 86, which when the set is in its active or ele vated position rests on a shoulder 87, formed by a horizontal slot 88 in the carrier 28, as shown in Figs. 5 and 12. By means of such finger-piece the set may be partially rotated to bring the finger-piece into a vertical slot 89 in the carrier, down which the fingerpiece may be moved to depress the set attached thereto. Springs 90, mounted on the front face of the carrier 28 and engaging the finger-pieces 86, are designed to hold the fingerpiece against accidental dislodgement when the sets are in their active positions. The outer sets are, like the sets 34, provided with plungers 36 and operate under ordinary circumstances in the same manner. The sections 49 and of the punch-block or anvil 47 cooperate with the outer independentlymovable lower sets 85, and it is to avoid the elevating of these sections when the inner sets only are active and consequent puncturing of the stock by the punches associated therewith that this sectional arrangement is provided. As shown in Fig. 4, the spring-controlled cross-head is provided with aper tures through which project the ends of the pins 54 of the bars 46 of the section 48, thereby connecting such bars with the bar 55. The outer bars 46, however, and consequently their associated punch-block sections, while normally under the influence of the spring-bar 55 are not affected when the inner sets alone are active. This result is attained by providing the ends of the bar 55 with shoulders 91, as shown in Fig. 4, with the under faces of which the pins 54 extending from the outer bars 46 engage when the outer sections are elevated and against which the bar exerts its pressure to hold the said anvil-sections depressed. the outer sets are thrown out of action, the inner punch-block or anvil section 48 is raised and the shoulders 91 simply moved away from the pins 54 of the slide-bars of the outer sections, leaving such sections stationary.

In our application for patent herein referred to we have shown and described a gage mechanism to be used in connection with an eyeleting-machine provided with a series of'eyelet sets and means for shifting the position of the gage automatically to center the same with reference to the sets when the number of active ones is varied. It will be readily understood that the same features may be adapted to the present machine without change and may be used with equally advantageous results. It is also to be understood that one pair only of cooperating sets may be employed instead of the hen, however,

series shown, in which case a single punchblock or anvil section and one punch would cooperate therewith.
